Selecting a Heat Pump.

Selecting a Heat Pump Water Heater

Heat pump water heater systems typically have higher initial costs than conventional storage water heaters. However, they have lower operating costs, which can offset their higher purchase and installation prices.

Before buying a heat pump water heating system, you also need to consider the following:
1.  Size and first hour rating -  To properly size a storage water heater—including a heat pump water heater with a tank— for your home, use the water heater’s first hour rating (FHR). The first hour rating is the amount of hot water in gallons the heater can supply per hour (starting with a tank full of hot water). It depends on the tank capacity, source of heat (burner or element), and the size of the burner or element. Product literature from a manufacturer may also provide the first hour rating. Look for water heater models with a first hour rating that matches within 1 or 2 gallons of your peak hour demand—the daily peak 1-hour hot water demand for your home.

Exploring Water Heater Options by Fuel Type

Fuel type and its availability in your area may narrow your water heater choices. The following is a list of water heater options by fuel or energy source:


  • Electricity

    Widely available in the United States to fuel conventional storage, demand (tankless or instantaneous), and heat pump water heaters. It also can be used with combination water and space heating systems, which include tankless coil and indirect water heaters.

  • Fuel oil

    Available in some areas of the United States to fuel conventional storage water heaters, and indirect combination water and space heating systems.

  • Geothermal energy

    Available throughout the United States to those who will have or already have a geothermal heat pump system installed in their homes for space heating and cooling. See Heat Pump Water Heaters for more information.

  • Natural gas

    Available in many areas of the United States to fuel conventional storage and demand (tankless or instantaneous) water heaters, as well as combination water and space heating systems, which include tankless coil and indirect water heaters.

  • Propane

    Available in many areas of the United States to fuel conventional storage and demand (tankless or instantaneous) water heaters, as well as indirect combination water and space heating systems.

  • Solar energy

    Available throughout the United States—most abundantly in the Southwest—for solar water heaters.

If you have more than one fuel type available in your area, it’s a good idea to compare fuel costs, especially if you’re building a new home. Even if you’re replacing a water heater, you may find that you’ll save more money in the long run if you use a different fuel or energy source. Contact your utility for current fuel costs or rates.

The type of water heater you choose will also affect your water heating costs. One type of water heater may use a fuel type more efficiently than another type of water heater. For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. Also, an electric heat pump water heater might have lower energy costs because of its higher efficiency than a gas-fired conventional storage water heater, even though local natural gas costs might be lower than the electricity rates.
